C. When deploying an Oracle RAC database:

Shadow clones should be explicitly disabled when deploying an Oracle RAC database. Oracle RAC requires highly consistent and low-latency storage access, and enabling shadow clones can introduce additional latency and potential inconsistencies that are unsuitable for such databases.

Shadow clones are designed to enhance performance for read-heavy workloads by caching frequently accessed data locally. However, Oracle RAC’s stringent requirements for data consistency and latency make this feature inappropriate for its deployment.

To address the performance concerns of a prospective customer evaluating a hybrid configuration versus an all-flash array, the following Nutanix features should be discussed:

Data Locality:

Nutanix ensures that data is kept local to the node where the VM is running. This reduces latency and increases performance by minimizing the distance data must travel over the network.

Automatic Data Tiering:

Nutanix can automatically move frequently accessed data to faster storage tiers (e.g., SSDs) and less frequently accessed data to slower storage tiers (e.g., HDDs). This ensures that critical data gets the performance benefits of faster storage without the need for an entirely all-flash array.

When an HDD fails, Nutanix's high availability (HA) system ensures the continuation of VM operations by initiating an HA event. The affected VMs will be restarted on a node that contains the replica data, ensuring minimal downtime and data availability​​.

Federal Government Encryption Requirements:

Compliance with strict encryption standards such as FIPS 140-2 is mandatory.

Required Items:

Self-Encrypting Drives (SEDs): Provide hardware-level encryption ensuring data at rest is encrypted.

Supported Key Management Server (KMS): Manages encryption keys in a secure and compliant manner.

Licensing and Software:

Nutanix Acropolis Pro Licensing: Necessary for certain advanced features but not directly related to meeting encryption standards.

Nutanix Software Encryption: Useful but hardware encryption (SEDs) and a supported KMS are essential for compliance.
